The invention discloses an Antarctic rare actinomycete Plantibacter sp. NJL1 and application thereof in promoting plant seed germination and/or seedling growth, and belongs to the field of microbial strains and application thereof. The Antarctic rare actinomycete Plantibacter sp. NJL1 is separated from marine sediments of South Pole Prydz Bay, has the stress tolerance characteristics of low temperature resistance, high salt resistance and the like, can promote plant seed germination, can significantly improve the effective germination rate of seeds when being applied to plant seed germination,enables seedlings to grow better, enables NJL1 to be colonized at the roots of the seedlings, changes the root morphology, increases root hairs, and is beneficial to nutrient absorption. Therefore, the Antarctic rare actinomycete Plantibacter sp. NJL1 can be developed into a crop seed germination regulator, and has application potential in agricultural production. 本发明公开了南极稀有放线菌Plantibacter sp.NJL1，及其在促进植物种子萌发和/或幼苗生长中的应用，
